Abraham Lincoln to Martin P. Sweet, 16 September 18581
Hon: M. P. SweetMy dear Sir
Yesterday Douglas and I met at Jonesboro– A very trifling thing occurred which gives ^me^ a little uneasiness– I was, at the suggestion of friends, putting in, some resolutions and the like of abolition caste, passed by Douglas’ friends, some time ago, as a Set-off to his attempts of a like character against me– Among others I put the questions to T. Campbell and his answers to them, in 1850 when you and he ran for Congress2 As my attention was divided, half lingering upon that case, and half advancing to the next one, I mentioned your name, as Campbell’s opponent, in a confused sentence, which, when I heard it myself, struck me as having something disparaging to you in it– I instantly corrected it, and asked the reporters to suppress it; but my fear now is that those villainous reporters Douglas has with him will try to make something out of it–3 I do not myself exactly remember what it was, so little connection had it with any distinct thought in my my mind, and I really hope no more may be heard of it; but if there should, I write this
(over)

<Page 2>
to assure you that nothing can be farther from me than to feel, much less, intentionally say anything disrespectful to you–
I sincerely hope you may hear nothing of it except what I have written–
Yours very truly.A. Lincoln4

2Martin P. Sweet had run as a Whig candidate for the U.S. House of Representatives in Illinois’ Sixth Congressional District against Democrat Thompson Campbell in the election of 1850. Campbell won the race, garnering 50.7 percent of the vote, while Sweet earned 48.7 percent. During the 1850 campaign, Campbell had been questioned on his positions on slavery, and Lincoln read the questions that had been posed to Campbell along with Campbell’s responses at the Lincoln-Douglas Debate in Jonesboro on September 15, 1858 as evidence of antislavery opinions held by allies of Stephen A. Douglas.
In his responses in 1850, Campbell had pledged that he would support bills prohibiting slavery in U.S. territories and in the District of Columbia, stated that he would oppose the admission of any slave states formed out of Texas or any U.S. territories, committed to voting for the repeal of the Fugitive Slave Act, promised to vote for a speaker of the U.S. House of Representatives who would organize the committees of that body “so as to give the Free States their just influence in the business of the legislation”, and asserted his belief that the U.S. Constitution conferred on the U.S. Congress the power to regulate slavery, and that the protection of human rights demanded the use of any constitutional means possible to prevent trafficking in enslaved people.

3During the Lincoln-Douglas Debate at Jonesboro, Lincoln ended his discussion of Campbell’s antislavery stances during the latter’s 1850 electoral race against Sweet by pointing out that both men had recently appeared at the Lincoln-Douglas Debate in Freeport on August 27, with Campbell present to support Douglas and Sweet to back Lincoln. As reported in the Republican-leaning Chicago Tribune, Lincoln stated that “when Judge Douglas and myself spoke at Freeport in joint discussion, there was his same friend Campbell, come all the way from California, to help the Judge beat me; and there was poor Martin P. Sweet standing on the platform, trying to help poor me to be elected.” In reporting this portion of Lincoln’s Jonesboro debate speech the Chicago Times, a Democratic organ, omitted the descriptor “poor” for both Sweet and Lincoln. According to that newspaper, Lincoln used the phrase “sneaking about” rather than “standing on the platform” to describe Sweet’s support of Lincoln. As described by The Daily Chicago Times, Lincoln immediately stated “I take back that ugly word” and told reporters “you must not put that in”, apparently referring to the phrase “sneaking about”.
Lincoln and Douglas debated at Jonesboro as candidates for the U.S. Senate. Lincoln, the candidate of the Republican Party, was challenging Douglas, the Democratic incumbent. Douglas would go on to defeat Lincoln and retain his seat. See 1858 Federal Election; 1858 Illinois Republican Convention.
